I TURN SHOE AND METHOD OF FIXING SHANK STIFFENER THERETO Filed Marph 14, 1929 Fatented Dec. 10, 1929 ,UNITED STATES PATENT" OFFICE REINHARD a iaam'nrs, or MELRosE, MASSACHUSETTS- TURN SHOE AND METHOD or FIXING snnNx STIFFENER r HnRE'ro:

Application filed March 14, 1929. Serial No. a 4e,990.

Turn shoes are commonly provided with reinforcements for the shank portions, such limit of forward extent and this shank piece is usually provided with a metallic shank stiffener which may be attached to its lower face. Such shank pieces are secured at the heel end of the shoe as by the heel nails and sometimes tacks are driven through its forward-"end into the sole. These tacks, however, form a very insecure bond, permitting the forward end of the shank piece to become loose almost immediately When the shoe is worn. Thus much of the reinforcing effect on the sole of the shank piece and stiffen-er is lost. It is quite undesirable, however, to pass fastenings through the shank piece near its forward end as the headed or protruding ends of such fasteners on the inner face of the shank piece are found to wear holes a through the sock lining and eventually through the stocking of the wearer.

In accordance with this invention, therefore, a means unexposed on the inner face of the shank piece is used to firmly secure the forward portion of the shank piece to the sole. To this end a securing device such as a rivet is passed through the sole and through the metallic stiffener and is headed over against the inner face of the stiffener 5 so that it does not extend through the shank piece. As the shank stiffener may be securely fixed to the shank piece as by means of attaching prongs at its ends which are clinched into the material of the shank piece, this fixing of the stiffener to the sole effectively secures the shank piece, preventing the sole from drawing away therefrom and I maintaining it'in the desired shape, improving both the appearance of the shoe after 4 some usage and also its wearing qualities.

For a more complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is a perspective of the shank plece with the stiffener shown in dotted lines, these parts being prepared for fixing to the shoe in accordance with the present invention.

I Figure 2 is a View partly in elevation and partly in :section ,of a shoe with the shank piece and stiffenersecured thereto.

Figure 3 is a detail section similar to a portion of Figure 2, but'to a larger scale.

F igures' l and 5 are detail views largely in section showing successivestages in the setting of a fastener of'a slightly different form than that. shown in Figure 3. y

, Referring to these drawings, at 1 is indicated a shank piece-of the usual form shaped to the general contour of the heel and shank portions of a shoe sole. To the lower face of this shank piece is shown attached a shank stifl'enerQ whichimay be of any suitable or usual form, preferably of metal, which as shown has attaching prongs 3 projecting therefrom which are clinched over in the material of the shank piece thus to fix the stiffener and shank piece. securely together but preferably without exposure on the upper face of the shank piece of any-attaching meansqThrough the shank piece 1 and the stiffener 2 are formed alined perforations 5 and 16, It is usually easier to form these perforations before the parts are assembled, but it may-be done afterwards if desired. The parts thus assembledare then placed in the shoe above the sole 10, as shown in i Figure: 2, in the usual manner,and the rear portion of the shank piece then or later on, as" may be found mostconvenienft, is secured in position, as', for example, by means of the 8 nails 11' which are used to securethe heel 12 in 'position. p 1.

j In alinement' with the perforation'sfi and 6 through the shank piece and stiffener, respectively, ahole is made through the sole as at 13 through which andtheholefi of the stiffenerflis'passed a suitable fastening device such as'arivet' 15', this rivet} being headed over against the upper face of the stiffener beneath the'shank piece so that itidoes not 5 protrude through the opening" '5; of the zhank piece ;but lies wholly beneath its upper ace,

If desired the hole 13 through the sole may be made, by theg-rivet'itself, -the partsbeing ably formed end face 19 which'acts to set the rivet 15 after it has been inserted in position through the sole and the stiffener. This rivet 15 may be of any suitable type such as the split rivet shown in Figures 4 and 5 or the tubular rivet as shown in Figure 3. Of course the rivet may, if desired, be inserted through a pie-formed hole in the sole before the setting operation is effected as is indicated in Figure 4. i

It will be seen that the rivet is driven.

through the sole somewhat back of the break line and in this position serves to hold the forward portion of the shank piece and stiffener firmly to the sole, the rear portion being secured as by the heel nail 11. Thus the sole is held tight to the shank piece and stiffener so that its shape is preserved and the appearance and Wearing qualities of the shoe much improved.

An embodiment of this invention having thus been described, it should be evident to those skilled in the art that various changes and modifications might be made therein without departing from the spirit or scope of the invention as defined by the appended claims.

I claim:

1. A turn shoe having a shank piece, a shank stiffener secured to the under face of said shank piece and overlying the sole of the shoe, and a fastener extending through said sole and stiffener and headed over on the upper face of said stiffener beneath said shank piece.

2. A turn shoe having a sole, a shank piece overlying said sole, a shank stifiener between said sole and shank piece and secured to said shank piece, means for securing the heel end of said shank piece to the sole, and a fastener located toward the forward portion of said shank piece extending through said sole and stiffener and headed over against the upper face of said stiffener and lying wholly beneath the upper face of saidshank piece.

3. A. turn shoe having a sole, a shank piece overlying said sole, a shank stiffener between said sole and shank piece and secured to said shank piece, means for securing the heel end of said shank piece to the sole and single rivet extending through the sole and stiflener and headed over on the upper face of said stiffener. i

4. The method of reinforcing a turn shoe,

which comprises fixing a stiffener to the lower face of a shank piece, and forming alined perforations therethrough, assembling the shank piece on the inner face of the sole of the shoe, and driving a rivet through the sole and shank piece and heading the rivet over on the upper face of said stiffener.

In testimony whereof I have affixed my signature.
